摘要

反向有機太陽能電池相較於正向結構具有較長的壽命且其可被應用於串聯太陽能電池上故本實驗以研究反向結構的電洞傳導層為主。本文首先測試傳導層對元件的重要性，發現傳導層可增加載子收集效率。之後對於正向和反向元件做各種電性維持壽命的實驗，証明反向結構具較長的壽命，再選用一批在文獻中有討論過且適合當電洞傳導層(HTL)材料做成薄膜和元件測試，發現相似構造的HTL(TTP和NNP)卻有不同電性和形態的表現，遂以表現最佳之材料，Pentacene，延伸其相似結構----DP-Pentcene和DB-Pentacene，討論其單層膜和在主動層上的特性，最後製成元件後討論造成短路電流不同的主因。

The inverted organic solar cells have longer lifetime and could potentially be applied for tandem cell applications. In this thesis, we have focused on studying the effect of hole transport layer (HTL) on the device performance of inverted P3HT:PCBM based solar cells. At first, we demonstrated the importance of HTL. The results revealed that HTL can enhance the carrier collection efficiency. Later, we have proved experimentally the life time of the inverted solar cell is longer than the standard structure. In order to study the effect of HTL, we synthesized and fabricated the thin film device using the HTL that had been discussed in the literature. We found that the HTL, namely TTP and NNP posses very different electrical transport and morphology, although both of them exhibit similar structure. Hence, we focused on studying Pentacene, as hole transport material, which gives the best device performance. Two types of Pentacene have been investigated: DP-Pentacene and DB-Pentacene that present similar structure. The physical properties of the deposited Pentacene thin film on substrate with and without active layer (blend P3HT:PCBM film) have been studied and discussed. Finally, we have discussed the possible reasons for the device short-circuit problem.
